摘要
Sodium beta-alumina ceramic and powder specimens having a range of Na2O content were studied by continuous wave NMR techniques. The 2 3Na-NMR spectra obtained were sensitive to composition. An ion exchange experiment showed the presence of sodium ions with distinctly different mobilities. The results suggest that some of the excess Na2O present in these ceramics is incorporated within the beta-alumina structure at a site distinct from that occupied by sodium ions in normal beta-alumina. © 1979.
